Quantitative detection for hydroxyl radicals in the process of advanced oxidation has become a crucial technical aspect for the study on dynamics and/or mechanism of organic material degradation in water treatment. In this paper, for the purpose to develop available methods that can be used conveniently in advanced oxidation process to treat organic materials presented in water, investigation and comparison of typical detection methods presented in broad research area were discussed, especially main results achieved in chemical and medical application were reviewed and assessed in detail. By necessary confirmation experiments, a method can be applied to processes of Fenton oxidation for water.
